Upgraded SumoSprings for Sprinter 2500

SuperSprings International (Carpinteria, California) announced new upgraded rear SumoSprings for Sprinter 2500 van and RV applications. Part number SSR-329-47 supersedes part number SSR-325-47. The ease of installation for the new part number is identical to the previous version. What has been upgraded is 50% more of SumoSprings’ patented micro-cellular urethane material is used for the new SumoSprings. This provides additional support and sway reduction, particularly for heavily loaded RV’s and vans. The added material increases the amount of energy the SumoSprings can absorb and dissipate, increasing ride comfort and driver control.

Correct, the SSF-106-40 (blue) are for a lighter load capacity. For the rear, we recomend going with the SSR-329-47 which are designed to improve overall driver control and ride comfort. Please see below for a direct links to the products in our store.

Hi John,

My name is Peter. First off, thank you for trying SumoSprings out! Now, regarding your question, every application is unique, so this does happen from time to time. The Sumosprings Solo kit is designed to leave anywhere from 1/4 of an inch to an inch of clearance between the SumoSprings, and the nearest contact point. The amount of clearance varies, but may be closer to that one inch mark on lighter applications (as you’ve seen with yours). We do have a couple other options available for a 2015 Sprinter 2500 2WD, but in order to recommend the best possible option, is there any way you’d be able to email me a picture of the current set-up? Preferably with the SumoSprings installed. My email is [email protected].

Once again, thanks for trying SumoSprings, and for contacting us. I look forward to hearing back from you.

We do not perform any installations here. We can recommend a couple nearby installers we are familiar with however. We are here Monday through Friday, from 8am to 5pm PST. Feel free to stop by when you can!

Hello there, I own a 2016 Sprinter 2500 passenger van, I have recently replaced ball joints, struts and shocks and fitted Michelin M+S tires.
However, my van rides hard on the front end, especially over bridge expansion joints and uneven pavement.
I want to buy the best ride improvement possible. i typically carry 5 or 6 people at most.
Any ideas?
